I'm on Long Island, and everyone is off.
For us, February break dates back to the Energy Crisis in the late 70's. At that time, there were two separate holidays this week. It became very expensive to close for two separate holidays, then have to reheat the schools. Sometimes there would be an additional snow day during the week... my daughter's birthday was Saturday and I don't remember a year when there wasn't snow on the ground on Feb. 17.
So just about all schools, including colleges, are closed this week. It's a lovely week off- no holidays to prepare for, just time at home.
And it should help tremendously in terms of the flu epidemic. We had SO MANY kids out last week.. in some of my classes I was averaging 12 kids out (out of 32-38 per class) one day about a week ago. Part of that was a combination of Senioritis and several papers due, but the kids (and faculty) are overwhelmingly sick. Hopefully someone is opening the windows in the unusually moderate weather, and hitting the whole building with Lysol.
